Theremin Schematics

Here's a list of various types of theremin schematics. You'll find tube theremins, transistor theremins, optical theremins, beginner, and advanced projects. If you're not sure where to start, we suggest reading through our theremin construction forum to get an idea of which schematic might be best for you.

Hand-drawn by Bob Moog, these schematics will give you insight into Prof. Theremin's original design concepts. schematic page 1, schematic page 2. Also available are the technical notes Bob Moog wrote while working on her theremin. Adrian Bontenbal also provided some additional tech notes on this circuit with details that are hard to make out from Bob's schematic as well as some bonus circuits.
